"We now know which area of the body females are looking at when they are making a judgment about male dance attractiveness," said Neave, a psychologist.

"If a man knows what the key moves are, he can get some training and improve his chances of attracting a female through his dance style," he said.

Neave and his team think head, trunk, wrist and knee movements show how healthy, vigorous and strong a man is -- and thus reveal his "reproductive quality," they said in a statement announcing their findings.

The findings are published Wednesday in the Royal Society journal "Biology Letters."
